Paper Mill Water Closure: A Success Story

Today the Pulp & Paper and Wood Products Industries are faced with tightening water quality and volume discharge regulations. Whether discharging to a local treatment facility or discharging to a river the economic impact is substantial. This article outlines a typical situation where the production facility utilized the latest expertise and most efficient equipment to cost-effectively achieve their water management goals.

APC Paper of New York produces specialty Kraft grades from recycled fiber. The Mill was faced with meeting new water discharge standards put in place by the New York Department of Environmental Conservation (NYDEC). The facility met all the new requirements except for Biochemical Oxygen Demand (BOD). To meet these guidelines the Mill commissioned consultants to review the process and determine the most cost-effective strategies to meet the new stringent requirements.

The Mill received recommendations and quotations to install a $1,200,000-$1,400,000 treatment system expansion. In addition to upgrading primary clarification, the Mill would be required to install a 500 GPM Secondary (Biological) treatment operation to meet the environmental regulations. After evaluation of the facilities process and regulatory requirements, World Water Works proposed a process water reuse approach that involved upgrading their present process Dissolved Air Flotation (DAF) system and installing advanced Microfiltration.

PROJECT DETAILS
LOCATION Buenos Aires, Argentina
CUSTOMER Central Puerto Power Plant
SOLUTION Complete Water Demineralization Plant
TECHNOLOGIES Ultrafiltration, Reverse Osmosis, Continuous Electrodeionization
A power plant in Buenos Aires needed to increase its demineralized water production and save money on operating expenses, but the poor quality of the available raw water from a nearby river made it difficult to make the switch from ion exchange technology to reverse osmosis (RO).

Greywater is an important non-conventional water resource which can be treated and recycled in buildings. A decentralized greywater recycling system for 223 inhabitants started operating in 2006 in Berlin, Germany. High load greywater undergoes advanced treatment in a multistage moving bed biofilm reactor (MBBR) followed by sand filtration and UV disinfection. The treated water is used safely as service water for toilet flushing. Monitoring of the organic matter degradation was pursued to describe the degradation...

BioLargo, Inc. (OTC: BLGO) held its third annual “AOS technical symposium” last month, hosting a group of scientists, collaborators, water industry experts, and government representatives, according to a recent post on the company blog. Prior AOS symposiums have updated stakeholders on the company’s progress with their innovative technologies for high performance, low cost, water treatment. Held at the University of Alberta and a nearby conference center, this year was different because it...
